Optical and Near-Infrared Spectroscopy of a High-Redshift, Hard X-ray Emitting Spiral Galaxy

Steve Dawson, Nate McCrady, Daniel Stern +4

We present optical and near-infrared Keck spectroscopy of CXOHDFN J123635.6+621424 (hereafter HDFX28), a hard X-ray source at a redshift of z = 2.011 in the flanking fields of the…
